The Coppock curve is a long-term price momentum indicator used primarily to recognize major bottoms in the stock market. Most technical market analysts consider the Coppock curve to be an excellent tool for discriminating between bear market rallies and true bottoms in the stock market.
Elementary calcium reacts with water. Calcium compounds are more or less water soluble. Calcium carbonate has a solubility of 14 mg/L, which is multiplied by a factor five in presence of carbon dioxide. Calcium phosphate solubility is 20 mg/L, and that of calcium fluoride is 16 mg/L.
Magnesium hydroxide Mg(OH) 2 is a strong base as are the hydroxides of the heavier alkaline earths, calcium hydroxide, strontium hydroxide and barium hydroxide. A solution/suspension of calcium hydroxide is known as limewater and can be used to test for the weak acid carbon dioxide.he hydroxide itself is insoluble in water, with a solubility product log K* sp of â11.7. Addition of acid gives soluble hydrolysis products, including the trimeric ion [Be 3 (OH) 3 (H 2 O) 6 ] 3+ , which has OH groups bridging between pairs of beryllium ions making a 6-membered ring.
